The transformer casing is made of polycarbonate (PC) material. The core is constructedfrom silicon steel sheets or amorphous alloy material, while the secondary windings areinsulated and heat-resistant electromagnetic wires. Based on the principle ofelectromagnetic induction, the transformer converts high primary current into lowersecondary current for use in AC circuits for current and energy measurement or metering.
